"Safe sleep" guidelines from the American Academy of Pediatrics say no loose blankets or quilts in a baby's bed. The group I sewed for used to make flannel blankets by he hundreds, but the nurses said no more since they didn't want to encourage their use when the babies went home. The isolottes (sp?) still have specialized blanket/quilts on top of them, but the sheets are fitted to the specialized cribs. I have also made dozens of covers for the position ears she mentions. There are lots of ways to sew for NICUs that aren't quilts.
